Why is it important to label blood specimens immediately after collection?

Labeling blood specimens immediately after collection is crucial for ensuring proper identification and preventing mix-ups. This practice helps maintain the integrity of the testing process by clearly associating the sample with the correct patient. Mislabeling or failing to label can lead to serious consequences, such as misdiagnoses or the administration of incorrect treatments, which can endanger patient safety. Immediate labeling safeguards against the potential for cross-contamination or confusion during handling and processing.

While compliance with hospital regulations is important, it primarily serves as a framework for practice rather than the primary reason for the immediate labeling. Sample sterility is a separate concern that relates to the technique of blood collection rather than identification. Tracking the time of collection is relevant for certain tests but is not the main reason for labeling specimens right after they are obtained. The foundational principle of preserving the identity of the sample and the patient is the driving factor behind this protocol.
